Multi phase bridge rectifier circuit with single phase input

摘要

The present invention provides a single phase input-three phase full bridge rectifier circuit of low cost and with wide power capacity range. The single phase input-three phase full bridge rectifier circuit comprises a pair of a.c. input terminals for receiving a single phase a.c. input voltage, a pair of d.c. output terminals for supplying a d.c. output voltage derived from the a.c. input voltage to a load connected to the d.c. output terminals, a series circuit connected between said a.c. input terminals and comprising at least a capacitor and an inductor connected together in series at a third terminal, and a multi-phase full bridge rectifier, said a.c. input terminals and said third terminal being connected to inputs of said bridge rectifier and said d.c. output terminals being connected to outputs of said bridge rectifier. $$
